Report of IPSEC tunnel uptime

[btp]

I have a customer that needs a report of the entire WAN - or at least of those spokes with <100% uptime during the last month. I have a dial-up hub-and-spoke-setup. I am pretty sure all data are in there, but I need some guidance on how to use them. Should I create a new dataset? Anyone done this and able to share some gory details?

I would like something similar to

| spoke hostname | tunnel uptime (availability %) | date/time tunnel down - up | 

                                                  | date/time tunnel down - up | 

                                                  | date/time tunnel down - up | 

| spoke hostname | tunnel uptime (availability %) | date/time tunnel down - up | 

                                                  | date/time tunnel down - up | 

nested like above if >1 tunnel down/up

Is this possible to achieve?
